(FILES) Students put their mobile phones in their lockers after switching them off in a highschool in Lorient, western France on September 5, 2024. France's president announced on November 28, 2025 that he would "probably" extend the ban on mobile phones to high schools from the start of the next school year, this measure already being in place in middle schools. The "phones on break" program aims to strengthen its application by requiring students to leave them during class in lockers, briefcases, or pouches if necessary.
